Application filed August 12, 1912. Serial No. 714,547.

To all whom it may concern:

Be it known that I, Gnoncr. It. EVERSON, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and tate of Ohio, haveinvented new and useful Improvements in Massage-Machines, of which thefollowing is a specification.

My invention relates to massage machines.

The objects of my invention are: 1. To afford a simple, practicalandinexpensive massage machine. 2. To afiord a simple, practical andinexpensive massage machine having a construction adapted to enable itto take on its driving or propelling power from some belt or wheel orsome other machine, preferably from the belt or hand wheel of a sewingmachine. I accomplish these objects by means of the mechanism disclosedin the following illustrations, of which:

Figure 1 is a side elevation of that portion of a sewing machine abovethe table thereof and a front elevation of my invention attached to thehand-wheel of said machine. Fig. 2 is a side elevation of the handwheelof a sewing machine and also of my invention connected-therewith. Fig. 3is a cross-section of the drive-wheel E, taken on the line bb, thesaddle-bearing and the friction wheel band or tire being eliminated.Fig. I is a side elevation of the saddle-bearing of my inventiontogether with the drive wheel workin therein and the connecting portionof the massage tube in longitudinal section. Fig. 5 is a side view ofthe metal coupling connecting the massage brush with the flexibledriving shaft. Fig. 6 is a side view of the flexible driving shafttogether with the metal coupling attached to each end thereof. Fig. 7 isa longitudinal section of the handle end of the massage tube togetherwith the parts immediately connected therewith. Fig. 8 is a plan view ofthe saddlebearing and drive wheel working therein together with thehand-wheel of a sewing machine, said hand-wheel having its upper portioncut away. Fig. 9 is a cross-section taken on the line a;a, Fig. 6.

Like reference characters represent like parts in all the figures.

In Fig. 1, A is the upper portion or sewing mechanism of a sewingmachine. B is the hand-wheel thereof. C is the table thereof. D is thesupporting tube of my invention. E is the drive wheel of my invention. Fis the bearing-saddle thereof. G is the rubber tube through which passesthe flexible driving shaft K, said tube connecting at one end with thehollow stud-coupling 16 over which the end of the tube passes, said tubeconnecting at its other end with the handle I-I into the end of whichsaid tube passes with a tight fit. I is a massage applicator. 1 is thebase plate of the supporting tube D.

In Fig. 2, the numerals 2 and 3 are the two leaves of a hinge heldtogether by the connecting pin 4. 5 is a setscrew passing normallythrough the upper leaf of said hinge but abutting the lower leaf thereofand being thereby adapted to elevate the upper leaf thereof, the lowerleaf of said hinge being screwed fast to the drop-leaf of the sewingmachine table. The base plate 1 is riveted fast to the upper leaf 2 ofsaid hinge. 6 is a flange extending laterally and integrally from thelower portion of the bearing saddle F, said flange having a downWard-extending stud-coupling 7 which extends integrally from the lowersurface of the free-end portion of said flange and passes into the upperend of the supporting tube D with a tight fit but at the same timeadmitting a free movement of said tube thereon. 8 is one of a pair ofslots cut through the upper end of said tube and entirely through themouth thereof, said slots being adapted to give flexibility to the upperend of said tube in receiving and working on said coupling-stud. 9 isthe rigid shaft that passes through the opening 13 of the drive wheel E,to which shaft said drive wheel is made fast by means of a screw orrivet passing through the opening 14 in the hub of said wheel and theopening 15 in said shaft. 10 is a rubber band or tire fitting into thechannel 11 of the drive-wheel E.

In Fig. 3, 11 indicates the channel in the drive wheel E. 12 is the hubof said wheel. 13 is the horizontal opening passing through said hub andadapted to receive shaft 9. it is an opening passing vertically throughsaid hub and adapted to receive a rivet or screw which fastens said huband wheel to the shaft 9 on which said wheel is mounted.

In Fig. 4, 16 is a hollow stud-coupling extending laterally andintegrally from the outside surface of the upper-end portion of one ofthe sides of said saddle-bearing. Said stud-coupling is tapered slightlytoward said terminates in a small opening axially alin r ing therewithand adapted to receive the shaft to which the drive wheel'E is attached.

In Fig. 5, J is a metal coupling adapted to connect the massageapplicator with the flexible driving shaft K. 19 is a base plate of theouter end of said coupling. 27 is studs, preferably a pair, extendingoutwardly from the outer face of said baseplate and adapted to fit intorecesses in the base of the massage applicator 1. 20 and 21 are inraised bearing surfaces of said coupling, and adapted thereby to reduceand minimize the friction of the outerend of the V handle H thereon.

In Fig. vb, K is a flexible driving shaft, made preferably of leather,and connecting at one of its ends with the coupling J and atthe'otherwith the coupling 17. The coupling 17 has an opening in one endadapted to receive the end of the flexible shaft K and described above.

one in the other end adapted to receive the shaft 9, and has also asmall opening passing transversely and axially through each end andadapted to receive small pins which fasten said coupling to each of itssaid members. 15 is a small opening passing transversely and axiallythrough the shaft 9,. which opening is adapted to aline with the opening14 in the hub 13 as 28 are fins, as to radial width beginning withnothing and increasing suitably in width as they proceed outwardly untilthey reach and connect integrally with the annular flange 29, said finsbeing adapted to cut their way into the handle H internally when saidbearing sleeve is driven into the end of said handle as aforesaid and toprevent said handle from revolving on said sleeve. 24 is an openingpassing transversely and axially through said sleeve-bearing and adaptedto aline with the opening 23 in said handle and admit of oil passinginto the bearing groove between said raised bearing surfaces 20 and 21of the coupling J and thereby lubricate the bearing of said sleeve onsaid coupling in a way to greatly reduce the liability of said oilworking out forwardly and spreading over the outer end of said handle,and the washer 30 which is riveted tightly onto the inner end of saidcoupling is adapted to prevent said oil from working out and spreadingover the inner surface of said handle I and also .over said flexibledriving shaft,'saidwasheris also adapted to confine and hold said sleeveon said coupling.

In Fig. 7, I is a massage applicator which is a special-cast rubber cup,the brim portion thereof extending outwardly. 25, a screw which, passingthrough an opening in the base of said applicator and into atapped"opening in the outer end of said coupling J,

is adapted to firmly bind said applicator to said coupling. between thehead of said screw and the base of said applicator and adapted toenlarge the bearing surface of the head of said screw thereon. 29 IS anannular flange on the outer end of bearing-sleeve 18 and adapted to givea suitable finish to the outer end of said 26 is a washer interveningthe supportingtube D, takes a plurality of positions of which 33indicates one. This lateral movement of said wheel gives a wider rangeforthe applicator I and besides overcomes to a certain degree theliability of bending said rubber tube and said driving shaft incasedthereby so abruptly near said wheel E as to check and stop the movementof said massage brush. This lateral movement of said wheelE also makesit possible to substitute a rigid driving shaft for said flexibledriving shaft. 7 V

In Fig. 9, 18 is the bearing-sleeve adapted to be driven into the outerend of the handle.

H. 28 are fins extending radially and integrally from the outer surfaceofsaid bearing-sleeve and adapted to cut their way into the insidesurface of the outer end of handle H and thereby prevent said handlefrom working loose, revolving and rattling 'on c said bearing-sleeve.

It is to benoted, that my invention can be geared up and' connected withthe belt of a machine, preferably a sewing machine, about 7 as well aswith the hand-wheel of said sewing machine, the belt of said machinework-.

ing and traveling in said groove 11 of said wheel E. It is to benoted-also that a variety of massage devices may be easily and quickly Vsubstituted for said applicator I. 7

Having described my invention by illustrations and in detail, I will nowdescribe it as a working mechanism. The stitching mechanism only of thesewing machine havingbeen disconnected, the machine is operated 1nconnection wlth my inventlonafter the same manner as 1t1s'operatedin'wlndlng a bobbin. By means of the set screw 5, the

drive wheel E can be given any degree of pressure against the hand-wheelB of the sewing machine. By means of friction between the aforesaidwheels, the wheel B communicates or transfers its power to Wheel E,which, in its turn, drives the flexible shaft Ii and the applicator I.The flexible shaft II, having reached the limit of its annularflexibility assumes a state of annular rigidity and revolves theapplicator I. In operating my invention, the operator sets or stands,treadling the sewing machine when sitting with one or both feet and withone foot when standing. The handle H of my invention is grasped witheither hand, and by means of the lateral movement of the saddle bearingF and the drive wheel E, the massage applicator I or other devicesubstituted therefor is given a range sufficiently wide to reach anypart of the body.

My invention, after the massage process is completed, can be detachedfrom the sewing machine in either one of two ways: (1) by detaching thesaddle-bearing F from the upper end of the supporting tube I); and (2)by removing the pin 4 and detaching every part of my invention abovesaid pin. In either instance, the remaining portion of my invention isnot in the way when the sewing machine is in use, and, besides, saidremaining portion being attached to a dropleaf of the sewing machinetable, can there by be let down and entirely out of the way when thesewing machine is not in use.

Having thus described my invention by illustrations, in detail and as aworking mechanism, what I claim is 1. In a massage machine, a couplinghaving a washer riveted securely to one end and a base-plate cast solidto the other end and an annularly grooved body between these extremes,said base-plate having studs projecting outwardly therefrom, saidcoupling having also an opening in each end and of different diametricalsizes, the larger of the two being adapted to receive the end of adriving shaft, and the smaller of the two being adapted to receive ascrew, said studs being adapted to fit into recesses in the base of amassage device.

2. In a massage machine, a coupling sleeve having an annular flange castsolid to one end and an oil hole in the body thereof, said flange beingadapted to give a finish to the outer end of a handle into which saidsleeve is driven, said oil hole being adapted to admit oil into thebearing of said sleeve on a coupling working therein, said sleeve havingalso fins projecting from, and eX- tending longitudinally along, theouter surface thereof, said fins being adapted to prevent the end of thehandle into which said sleeve is driven from turning on said sleeve,said sleeve being adapted to afford a suitable bearing between the endof a handle and a coupling working therein.

3. A massage machine consisting of a hinge-like structure removablyattached to any suitable point of another machine, adjustable means forsuitably elevating and lowering the free leaf of said hinge-likestructure, a tube mounted endwise and upriqhtly on and securely attachedto the free leaf of said hinge-like structure, a saddlebearing mountedon said tube and adapted to oscillate laterally thereon, a shaft mountedon said saddle-bearing, a drive-wheel mounted on and securely attachedto said shaft and a rim of any suitable wheel of said first mentionedmachine.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
